NSI has developed and launched a Code of Practice for the design, installation and maintenance of scaffold alarms. Code of Practice NCP 115 has been created to help improve the security of buildings in vulnerable circumstances. The installation of scaffold alarms is a growing market, but to date has never been the subject of any form of self-regulation or industry-specific standards. Scaffolding often represents a weak-spot on buildings, and affords the intruder or trespasser a potential method of entry. The NSI Code will provide an aid for those with an interest in the security of buildings or the reduction of accidents, to help mitigate risks during periods of vulnerability when repairs or restoration work are being carried out.
